Question

Which of the following enzyme is concerned with the transfer of electrons?

• A. Hydrolase
• B. Dehydrogenases
• C. Transaminases
• D. Proteases

Answer 1

The correct option is B Dehydrogenases

Enzymes are the biocatalyst. Most of the enzymes have been classified into different groups based on the type of reactions they catalyze. They are as follows-
(i) Oxidoreductases/ dehydrogenases: The enzymes catalyzing oxidation and reduction between two substrates S and G involving gain or loss of electrons are known as dehydrogenases.
(ii) Transferases: The enzymes catalyzing the transfer of a group, G (other than hydrogen) between a pair of substrate S and S are known as transferases.
(iii) Hydrolases: The enzymes catalyzing hydrolysis of ester, ether, peptide, glycosidic, C-C, C-halide or P-N bonds are known as hydrolases.
(iv) Lyases: The enzymes that catalyzes the removal of groups from substrates by mechanisms other than hydrolysis leaving double bonds are known as Lyases.
(v) Isomerases: The enzymes that catalyzes inter-conversion of optical, geometric or positional isomers are known as isomerases.
(vi) Ligases:The enzymes catalyzing, the linking together of 2 compounds are known as ligases.
So, the correct answer is option B.
